Title: Track access device
Inventor: SASAKI TAKESHI
IPC: G11B21/08
Filed: 1995-05-23
Abstract: PURPOSE: To prevent a tracking servo pull-in operation from becoming unstable and an access time from becoming late when the neutral position of a convergent lens is extremely shifted. CONSTITUTION: At the time of the access operation to a target track, a value added with the external force correcting value of a convergent lens supporting spring being the mean value of lens actuator driving command values in the ON state of a lens locking servo is made to be the output value to a D/A converter 10 with respect to the lens actuator driving command value calculated by a DSP 8, that is, the calculated output value to the D/A converter 10. Consequently, even when the neutral position of the convergent lens is extremely shifted by the incination of an optical recording and reproducing device and the deformation of a convergent lens holding leaf spring, etc., the control interference due to the external force of the convergent lens holding leaf spring is cancelled with a simple circuit constitution and a stable access performance is obtained and also the shortening of the access time is made possible.

Title: Fluorine-containing elastomer
Inventor: YAMASHITA EIICHI
IPC: C08F214/26
Filed: 1987-05-22
Abstract: PURPOSE:To obtain a fluorine-contg. elastomer which has specified physical properties and is excellent in processability, thermal aging resistance, oil resistance and freeze resistance, by copolymerizing tetrafluoroethylene, an alkyl group-contg. vinyl ether and other vinyl monomer. CONSTITUTION:The title product is a fluorine-contg. elastomer consisting of about 30-60mol.% tetrafluoroethylene, about 30-55mol.% 3-8C alkyl group- contg. vinyl ether and about 1-20mol.% other vinyl monomer copolymerizable therewith, and comprises a copolymer having a glass transition temp. of 0 deg.C or lower and a Mooney viscosity [ML1+4 (at 100 deg.C)] of about 20 or higher. The other vinyl monomers copolymerizable include, pref., halogen-contg. or epoxy group-contg. vinyl monomers. Said copolymer becomes inferior in flexibility and brittle resistance at low temp. when its glass transition temp. exceeds 0 deg.C, and is not suitable for conversion into an elastomer. If its Mooney viscosity is less than about 20, the blending ingredients stick onto the roll surface, and cannot be blended nor processed well.

Title: Digital-analog converting circuit
Inventor: KOGA IZUMI
IPC: H03M1/10
Filed: 1983-07-07
Abstract: PURPOSE:To obtain an analog output voltage where a gain drift is corrected by temperature change by using an output of an error detection circuit to adjust a gain of a D/A converting section. CONSTITUTION:A high speed D/A converter 10 converts a digital data 11 into an analog data and outputs 13 the said data. When an input data crosses a predetermined setting value, an input detecting circuit 20 gives a trigger signal to a sample holding circuit 30. Then an error detection circuit 50 compares an output of the circuit 30 with a voltage of a reference voltage generation circuit 40 and when both signals has a difference, the circuit 50 generates an error signal and gives it to a reference voltage adjusting circuit 60. The gain of the converter 10 is adjusted by changing a reference voltage Vref fed to the converter 10 so that the error signal inputted to the circuit 60 is made zero. Thus, the gain drift of the converter 10 is corrected.

Title: Grid-shaped reflection mirror antenna system
Inventor: MASHIMA RIKIHIKO
IPC: H01Q15/14
Filed: 1992-05-18
Abstract: PURPOSE:To prevent a grid-shaped element of a grid-shaped reflection mirror from being due to vibrations by providing the grid-shaped element with elasticity and making it extendable and contractable. CONSTITUTION:A grid-shaped element 21 is formed in the shape of bellows continuously to circular recessed parts 26 and 27 projecting parts 27 in the portion other than support welding parts 24 and 25. This element 21 can be used for the entire face of the grid-shaped and cup-shaped reflection mirror antenna system. The respective parts in the shape of the entire bellows are slightly and elastically deformed by the circular recessed parts 26 and projecting parts 27 corresponding to the strength of wind speed, and secondary vibrations are prevented from being generated. On the other hand, since the grid-shaped element 21 is elastically deformed between circular precessed parts 26 and projecting parts 27 concerning the deformation caused by wind speed, it is slightly deformed as a whole, and the deformed parts are distributed and prevented from being concentrated to the support welding parts 24 and 25. Although such deformation is disordered rather than the case of exactly forming the parabolic plane of the element 21, it is set within the allowable range corresponding to the wavelength of a used frequency band, and since the circular recessed parts 26 and projecting parts 27 are formed, eddy current caused by the passage of wind is changed so as to hardly generate the specified vibrations.
